Factory aquaculture is the main production model for intensive aquaculture nowadays, and with its precise feeding performance, the automatic feeding system is one of the most important supporting equipment in intensive factory aquaculture, which can not only reduce feed waste and labor intensity, but also relieve environment pollution. This paper introduces the structure of automatic feeding system, analyzes the present research situation of the automatic feeding system from the aspects of loading transporting system and blanking dripping system elaborates the characteristics, problems and countermeasures of two kinds of mostly adopted centralization automatic system, i.e. pneumatic remote transmission and rail transmission systems.   Through the study, it is believed that the closed-loop remote management and control system that integrates water quality monitoring, automatic feeding device and feeding decision system lines with the future development trend. .
